AE 404 - "And the heaven departed as a book rolled up"

AE 404 Revelation 6:14
And the heaven departed as a book rolled up,
signifies that the spiritual man became closed up.
This is evident from the signification of "heaven,"
as being the church in general and in particular;
for the church is the heaven of the Lord on earth;
moreover the church makes one with heaven by conjunction;
therefore when "heaven and earth" are mentioned in the Word,
the church internal and external is meant,
for the internal of the men of the church is heaven with them,
and their external is the world with them.
